UNITED STATES' PATENT IFF-ICE@ JOSEPH HOFFMAN, OF NEW YORK, N. Y., ASSIGNOR TO JOSEPHA REOKEN- DORFER, OF SAME PLACE.

LEAD AND CRAYON HOLDER.

SPECIFICATION formingpart of Letters Patent No. 228,897, dated June 15, 1880.

Application filed May 8, 1880.

To all whom it' may concern Be it known that I, JOSEPH HOFFMAN, of the city, county, and State of New York, have invented certain new and useful Improvements in Lead and Crayon Holders, of which the following is a specification.

My invention has relation to that kind of lead and crayon holders of which the device shown and described in Letters Patent No.

1o 215,521, ofMay 20,1879, reissued November 1S, 1879, No. 8,967, may be considered the type. In that patent the lead-containing tube or receptacle is attached to and movable with the jaws. In other patents subsequently applied I5 for and obtained by me the lead-holding tube has in some instances been movable with the jaws, and in some instances independent of thejaws; but in no case of which I have knowledge in the class of holders referred to has 2o there been a lead-containing tube or receptacle attached to or forming part of the handle combined with lead-holding jaws movable longitudinally independently ofthe handle. This arrangement in some kinds of pencil-holder may be used to advantage-as, for instance, where it is desired to use a receptacle made of one kind of material with jaws made of a different material or metal. To this end I have devised theimprovement illustrated in the accompanying drawings, which I shall now proceed to describe.

Figure l is a longitudinal central section of a lead or crayon holder embodying` my improvements. Fig. 2 is a like section of the same in a plane at right angles with the plane of section in Fig. l. Fig. 3 is a transverse section on line a' fr, Fig. 1.

A is the tubular sheath or handle, terminating in a tapering or contracted metal tip, b. 4o lVithin the sheath is a lead-containing receptacle, consisting, in this inst-ance, of the tube B, which is fastened permanently to the handle by suitable means, here shown as consisting of a pin, a, passing through the tube into the handle. The tube terminates some distance short of thefront end of the tip b.

In advance of the tube are the lead holding or clamping jaws C, tapered or provided with inclines, and having biting-edges, as usual.

5o These jaws are longitudinally movable, so as (No model.)

to be moved against or away from the contracted front end of the tip b, according as it is desired to clamp or release the lead held be tween the jaws. They may be thus moved by any suitable instrumentality arranged to be operated from the exterior of the haudle-as, for instance, by a sliding sleeve connected to them by a pin or other means extending through a longitudinal slot or slots in the tip or handle. The preferred arrangement, how- 6o ever, is shown in the drawings. Each jaw is connected to or mounted on the end of a rod,

c, which extends back between the lead-tube and the handle, and is connected at the rear to a cap, D, adapted to slide back and forth on or in the rear end of the sheath.

Vithin the cap, and encircling the two rods c, is a spiral spring, d, which is under com pression, bearing at one end against the sheath or handle and at the other end against the cap, 7o thus serving normally to force the cap back, and consequently to cause thejaws to close or contract. By pressing on the cap it, together with the rods c and jaws O, will be moved forward, thus permit-ting theA jaws to spread and release their bite on the lead.

The tube B may be made as shown in the drawings, or may be a shorter tube, formed and arranged to guide and afford free passage for the lead from the jaws to a receptacle in 8o the interior of the handle back ofthe tube, or vice versa.

The jaws may be of any desired shape in cross-section, either round, square, or polygonal.

Vhat I claim, and desire to secure by Letters Patent, is-

1. In a lead or crayon holder, the combination, substantially as hereinbefore set forth, of

the handle, the lead tube or receiver within 9o and attached to the same, and lead-clamping jaws longitudinally movable with respect to said handle and tube.

2. In a lead or crayon holder, the combination, substantially as hereinbefore set forth, of the handle, the lead tube or receiver within and attached to. the same, the lead-clamping jaws, longitudinally movable with respect to the handle and tube, and means, substantially as described, arranged and operated from the roo exterior of the sheath, to effect said movement tube and handle, connecting the cap with the Io of thejaws. jaws.

3. In a lead or crayon holder, the coinbinaln testimony whereof I have hereunto set tion,snbstantially as hereinbefore set forth, of l my hand this 7 th. day of May, 1880. the handle, the lead tube or receiver within 5 and attached to the handle, the lead-clamping JOSEPH HOFFMAN jaws, longitudinallyl movable with respect to Witnesses: the handles and tube, the sliding cap and G. S. BRAISTED, spring', and the rods intermediate between the JOE WV. SWAINE.
